-'4.0M V Y IMPROVEMENT IN' HAY AND COTTON-PRESSES. l

The Schedule referred to in these Letters Patent and making part of thename.

To allwhom it may concern:

Beit known that I, WILLIAM G. Banks, of Como Depot, in the county ofPanola, and State of Mississippi, have invented a new and improvedCotton and Hay-Press and I do hereby declare that the followingis afull, clear, and exact description of the construction and operation ofthe same, reference being had to tlccbmpanyin g drawings, making a partof this specification, in which- 1 Figure 1 is a side view, showing laportion inA section.

Figure 2 is a side view. v

lhis invention relates to that form of press patented by W. C. Banks,June 1'8, l1867, No. 155,865, the es-I sential principle of which is,that the block that supports the screw is capable of being moved asidewhen the platen is raised, so as to leave the top of the press- ,boxunobstructed. f

This invention relates to an improved arrangement for operating themovable supporting-block referred to.

' In the drawings- A represents the four corner-posts of the frame;

B B, the cross-beams uniting'said posts;

O, the press-box, in which the bale is formed c c, the hinged sidesofthe press-box, held together by rods a a, made thin and at, andprovided with ay head at each end, the flat thin Ablade sinking into anopen slot in the edge of the doors c c, and' the heads coming againsttheir outer faces, so' as to prevent them from opening. y y

D, the conducting-tube above the press-box, through which the platenpasses, up and down;

E, a screw-rod, rigidly fixed to the platen, so as not y to 'be capableof turning;

F, a rotating screw-uut, surrounding a portion of the screw-rod, and, byits rotations, moving the rod up or down; f

G, the supporting-beam, hereinbefore referred to, which sustains thescrew-nut F, and furnishes it a bearing;

H, a beam, attached to the screw-nut, for the purpose of affording meansto turn'itin its bearings;

their upper ends, directlyl over the screw-rods, where 'a hole isprovided, to allowfit to rise through them, and attached to theouterends of beam H, at h h;

K, the awning or canopy, supported on a'frame attaohed to sweeps I J andbeam H; and

L L L L, four levers, pivoted to the posts A A, at l l, and connected tothe ends of beam G by means of chains g g, by which the beam G can he`slid from one I J, two inclined sweeps, connected together at;

l side'to the other, so as to bring the .platen to any del sredposition. i

When not in use, the levers hangv vertically, as

bering the instrument, either in appearance, or, in fact. Theconstruction of the screw-nut F and its bearings is as follows: Agroove, m, is cut around the nut, at the point that is to come at theupper edge of the'supportingbeam, and a flange or collar, or., is formednear the lower end of the nut, its under side coming in the same planewith the under surface of the beam.

A gain, o','is cnt vin the-under side of the beam, around the holeoccupied by the nut and screw-rod.

4Into this gai na metallic plate, Rfis inserted, having ridges 'fr ratits ends, slightly thicker than the ange n.A f vThe' plate E is slippeddown over the screw-nut till seen in fig. 1.

The eridof the nut below-the collar now projects downa short distance,and another plate, S, is slipped over it, and brought up against theridges fr Jr, where itfis' fastened by screw-bolts, so that the collaror flange is confined between the two plates 1tl S, free to turn, butincapable of rising or falling. This secures the nut in place, and'enables it to operate the screw-rod after the latter has. beeninserted, in the manner and for the purposes above indicated. 1 Inorder, however, to hold the nut still more firmly, and to afford myselfthe means of adjusting its bearthe upper surface of the beam G,designated, respectively, 'w w', each being fastened with screws, andthe, two capable of being Ldjusted toward or from each other, atpleasure, by moving the screws.

The adjacent edges oi' these two plates are cut away, so as to fit tothe-sides of the nut within the shown, being entirely out of the way,and not encunrit rests on the collar, and is then raised, by means of ythe nut, until it reaches its position in the gain, as

ings as it wears away, I employ two other plates on plicated apparatusheretofore employed, is well illus- A.trated by comparing the upperbearing, composed of the two small half plates w w, with the lowerbearing, composed of the two large plates R S, the collar between them,and the gain o, in which they operate, itself one of the simplestbearings heretofore made for a similar purpose.

The advantagein point; of simplicity, cheapness, lightness, andadjustability, is, obviously, with the upper bearing. y

Having thus described my invention,

What I claim as new, and desire to secure by Let;-

ters Patent, is-

The `arrangement; of the four levers L L L L, two at each end of thebeam G, pivoted, at theinupper end, to the frame of the press, andconnected, by chains g g, or equivalent device, to the ends of saidbeam, substantially as and for the purposes specied. d
